Library Concepts
& DIAKON Systems, LLC

Library Concepts, formerly known as Diakon Systems, is responsible for the design and development of two library automation software systems, PC Card Catalog and CONCEPT I. The company maintains the primary sales and support functions for these products.

DIAKON Systems was established in the early 1983 as a custom software design company. Early products included PC-based software supporting banking, city government, printing, office supply sales and inventory tracking activities.

Its early library management development began in 1984 with a shareware product called CASSY, designed to print catalog cards and Accession/Shelf lists. This product had its initial impetus because of a personal involvement with church library work. At the time, there were no inexpensive PC software packages that could manage catalog cards. Hence the need.

In 1987 DIAKON Systems developed a more advanced system called LIBRARY MANAGER for marketing mostly to church libraries by another firm.

The company expanded the original CASSY program to the DOS product named PC Card Catalog: professional. This was available in 1989. As Windows evolved into the operating system of choice, the product was redesigned for the Windows 95/NT platform.

In 1998 PC Card Catalog:Windows was released. This program has been under constant update and development since that time as seen by the recent release of version 3.4 and CONCEPT I.

The program name was shortened to PC Card Catalog when version 3.0 was released (April 2002). Since 2003, our company has been known as Library Concepts.

The development and testing have revolved around an actual library at a church, Wedgwood Baptist in Fort Worth, Texas, where the Library Concepts principles are active.
